Abstract
The Shenzhen Vanke Center is constructed of a composite frame and cable system, which is a novel structural system and leads to a tedious, complex, and lengthy construction process. The structural construction process simultaneously affects the shape of the Shenzhen Vanke Center and the final structural force state. To control the construction process and make sure the construction is safe, a structural health monitoring system for the Shenzhen Vanke Center construction has been implemented, which includes monitoring of the cable tensioning phase and superstructure construction phase. In this paper, the Shenzhen Vanke Center and its construction process are first introduced. The monitoring data for a standard unit of the whole structure was selected for study. For the cable tensioning phase, these data include the cable forces, strains of the bottom floor’s steel beams, and concrete-filled steel column and structural displacements; for the superstructure construction phase, the data include the cable forces and structural displacements. According to this monitoring data, a comprehensive understanding for the performance of the structure and key members in the construction phase are shown and discussed. The analysis results indicate that the construction monitoring system of the Shenzhen Vanke Center is stable and reliable. It also has many functions, such as to guide the cable tensioning, to grasp the changes in strain of key members, to control the structural construction deformation, to conduct the construction process, and to ensure safe structural construction.
